However, although the light field camera increases the above-mentioned flexibility of single-exposure imaging, it records the viewing angle direction information of the object light by losing the spatial resolution of the image. Therefore, when shooting a 3D scene based on a light field camera, the captured The spatial resolution of the image will be greatly reduced

Embodiment Construction
[0038] Exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.
[0039] Here, it should also be noted that, in order to avoid obscuring the application due to unnecessary details, only the device structure and / or processing steps closely related t...

The embodiment of the application discloses a light field acquisition control method and device and light field acquisition equipment. The light field acquisition control method comprises the steps that at least one child lens influencing light field acquisition of a first region in the child lens array of a light field camera is determined, and the first region is a local part of a scene to be photographed; a region to be adjusted of the image sensor of the light field camera is determined according to at least one child lens; pixel density distribution of the image sensor is adjusted so that the average pixel density distribution of the region to be adjusted is different from the average pixel density distribution of other regions of the image sensor; and the adjusted image sensor performs light field acquisition of the scene to be photographed. According to the technical scheme, the overall pixels of the image sensor are fully utilized to perform light field acquisition, and light field acquisition efficiency is enhanced so that the actual diversified application requirements of users can be better met.
Description
technical field [0001] The present application relates to the field of light field acquisition technology, in particular to a light field acquisition control method and device and a light field acquisition device. Background technique [0002] A light field camera is an imaging technology that uses a sub-lens array to record and reproduce a three-dimensional scene. It usually places a sub-lens array between the main lens and an image sensor such as a CCD. Light field information is recorded on the focal plane of the sub-lens array. [0003] Different from the two-dimensional image acquisition method of the traditional camera, the light field camera can record four-dimensional light field information such as the space and angle of view of the three-dimensional scene through a single exposure, and supports "focusing after shooting" (that is, no need to focus when shooting), through Rich image effects can be generated by processing the captured images, which can meet various i...
